    Abstract:
    Haemangiopericytomas (HPCs) are rare vascular tumours that commonly involve the soft tissues of the trunk and lower extremities. In the head and neck, the most common sites are the nasal cavity and the paranasal sinuses, and unusually, the orbital region, the parotid gland, and the neck. We report a patient with HPC that originated in the infratemporal fossa and involved the pterygopalatine and the middle cranial fossae, apparently the first such case to be reported. Although the patient has undergone resection on three separate occasions, the tumour recurred. We then performed an extended resection using the infratemporal fossa approach type D. The patient has shown no recurrence in the past five years. Although histopathologic confirmation of this malignancy may be difficult, extensive resection remains the most effective treatment in such cases.
